For this reason, in any case, when it is desired to absorb the liquid without leaking, the absorbency having a size covering a position covering the front side from the portion where the liquid flows out to a position covering the groove portion of the body, for example, around the tailbone Goods are needed.
JP 2003-79662 A

  The conventional absorbent article as described above can absorb the liquid flowing out in a wide area regardless of the posture of the user and suppress leakage, but the size of the absorbent article itself is increased, so that it is portable. There is a problem that is bad.

  This invention is made | formed in view of the above conventional problems, Comprising: It aims at providing the absorbent article which can absorb a liquid effectively, suppressing size small.

  In order to solve the above-described problems, the main present invention includes an absorbent body having a liquid absorbent member for absorbing liquid, and an absorbent article body in which the absorbent body is stacked along the longitudinal direction. The absorbent article is characterized in that the liquid absorbent member of the absorbent body is provided so as to protrude in the longitudinal direction from the outer peripheral edge of the absorbent article main body.

  ADVANTAGE OF THE INVENTION According to this invention, it is possible to provide the absorbent article which can absorb a liquid effectively, restraining size small.

  This specification and the drawings disclose at least the following matters.

An absorbent body having a liquid absorbent member for absorbing liquid, and an absorbent article main body on which the absorbent body is stacked along the longitudinal direction, wherein the liquid absorbent member of the absorbent body is the absorbent. The absorbent article is provided so as to protrude in the longitudinal direction from the outer peripheral edge of the article body.
According to such an absorbent article, since the liquid absorbing member of the absorbent body protrudes in the longitudinal direction from the outer peripheral edge of the absorbent article body, the projected absorbent body is wider than the absorbent article body in the longitudinal direction. Liquid can be absorbed in the region. At this time, since the absorbent article body has a shorter length in the longitudinal direction than the absorbent body, the size of the absorbent article can be made smaller than when the absorbent body and the absorbent article body are formed to have the same length. . For this reason, it is possible to realize an absorbent article capable of effectively absorbing liquid while keeping the size small.

In such an absorbent article, the width of the absorbent body in the direction intersecting with the longitudinal direction is preferably narrower than the width of the absorbent article body in the direction intersecting with the longitudinal direction.
According to such an absorbent article, since the narrow absorbent body protrudes, it is possible to effectively absorb the liquid by allowing the absorbent body to enter the narrow part. Such an absorbent article is used, for example, to absorb liquids such as menstrual blood, but by placing a narrow absorbent body along the groove of the body and arranging it, the liquid flowing along the groove is allowed to flow. It can be absorbed.

In such an absorbent article, the absorbent body may be bonded to the main body of the absorbent article such that one end portion in the longitudinal direction is non-peelable and the other end portion is temporarily bonded so as to be peelable. desirable.
According to such an absorbent article, the other end part temporarily bonded so as to be peeled off is peeled off so that the absorbent body is bonded to the absorbent article main body only at one end part. Is possible. And it is possible to isolate | separate the edge part side which the absorber peeled from the absorbent article main body. For this reason, for example, when the absorbent article is used to absorb liquid such as menstrual blood, the absorbent body can be separated from the absorbent article main body and surely enter the body groove to absorb the liquid. Is possible.

In this absorbent article, the other end of the absorbent body is peeled from the main body of the absorbent article, and the other end is opposite to the joint on the one end in the longitudinal direction. It is desirable that the absorbent body is protruded from the outer peripheral edge of the absorbent article main body by moving the absorbent body to the outer periphery.
According to such an absorbent article, before making an absorber peel from an absorbent article main body, an absorber does not protrude from an absorbent article main body. Moreover, the absorbent body is protruded from the outer peripheral edge of the absorbent article main body by moving the absorbent body peeled from the absorbent article main body in the longitudinal direction beyond the joint portion on one end side to the opposite side. For this reason, before the absorbent body is peeled off, to achieve an absorbent article capable of effectively absorbing liquid by protruding the absorbent body from the absorbent article body after peeling while keeping the size small. Is possible.

It is this absorbent article, Comprising: The said absorber is good also as the area | region which overlaps with the said absorbent article main body being joined so that peeling is impossible.
According to such an absorbent article, in the part where the absorbent body and the absorbent article main body overlap, by receiving the liquid that could not be absorbed by the absorbent body in the absorbent article main body, While realizing a structure that prevents liquid leakage, it is possible to absorb liquid leaking along the longitudinal direction at a portion of the absorbent body protruding from the absorbent article body.

In such an absorbent article, a liquid-impermeable member is provided on a surface of the absorbent article main body on which the absorbent body is not joined and at least a projecting portion of the absorbent body. It is desirable.
According to such an absorbent article, the portion where the absorbent body and the absorbent article main body overlap is caused by the liquid impervious member provided in the absorbent article main body, and the portion protruded in the absorbent body is protruded. The liquid impervious member provided at the site can prevent liquid leakage from the absorbent body and the absorbent article body.

In this absorbent article, it is preferable that the absorbent article main body includes another absorbent body different from the absorbent body.
According to such an absorbent article, the liquid can be absorbed by the absorbent article main body and the absorbent body. Such an absorbent article is used, for example, to absorb liquids such as menstrual blood, but by placing a narrow absorbent body along the groove of the body and arranging it, the liquid flowing along the groove is allowed to flow. It is possible to absorb, and the liquid flowing straight downward can be effectively absorbed by the absorbent body and the absorbent article body.

It is CC sectional drawing in FIG.

<< absorbent article >>
As shown in the drawing, an absorbent article 1 in the present embodiment has a shape that is long in a predetermined direction, and a base absorbent body 10 as an absorbent article body that has a substantially rectangular shape for absorbing liquid such as menstrual blood, and a base A top absorbent body 20 as an absorbent body which is bonded to the back surface sheet 30 provided on the back surface of the absorbent body 10 and the surface of the base absorbent body 10 and is disposed along the longitudinal direction at the center in the width direction of the base absorbent body 10. And. The back sheet 30 is provided to prevent leakage of liquid to be absorbed by the base absorbent body 10 and the top absorbent body 20 to the back surface side.

  In the present absorbent article 1, the body excretion opening that is assumed to be on the center line in the width direction of the absorbent article 1 and on the front end side from the center in the longitudinal direction of the body excretion opening portion. The site | part contact contact position Z is located. In other words, the absorbent article 1 is formed such that the length on the rear end side from the assumed body excretion opening part contact position Z is longer than the length on the front end side from the assumed body excretion opening part contact position Z.

  In the base absorbent body 10, an absorbent body material 12 a as a liquid absorbent member having pulverized pulp obtained by pulverizing sheet-like pulp, a superabsorbent polymer, and heat-fusible fibers is used as a thin paper (not shown) such as tissue paper. An absorbent body 12 as another absorbent body wrapped in a sheet with a predetermined thickness, and a surface sheet 14 attached to the surface of the central portion in the width direction of the absorbent base 12. Yes. The thin paper and the surface sheet 14 are both liquid-permeable sheets. Further, the thin paper is a sheet finer than particles of the superabsorbent polymer, and prevents the superabsorbent polymer from leaking from the absorbent body 12 to the outside. Since the surface sheet 14 is located on the surface side in contact with the body, a sheet softer than the thin paper is used.

  The length of the longitudinal direction of the base absorbent body 10 is such that the perineum is sufficiently covered on the rear side from the position of about 40 mm ahead of the body excretion site contact assumed position Z when worn, The overall length of the absorbent body 10 is set to about 220 mm like an absorbent article generally used as a so-called regular size for daytime.

  The back sheet 30 is a thermoplastic and liquid impermeable sheet such as polyethylene or polypropylene. The back sheet 30 is formed sufficiently wider than the base absorbent body 10, and is extended outward in the width direction on both sides in the width direction to a predetermined region centered on the body excretion opening portion contact estimated position Z in the longitudinal direction. A holding portion 32 is formed. Further, the back sheet 30 and the base absorbent body 10 are subjected to a round seal process in which the outer peripheral edge portion of the absorbent article 1 is thermocompression-bonded at least at the front end portion and the rear end portion. Here, the end portion indicates not only the end edge (edge) of the contour portion but also the vicinity including the end edge. For this reason, the edge is not necessarily joined at one end part to be joined and the other end part to be temporarily joined. The same applies to the “end” in the following description.

  A release sheet 34 (FIGS. 2 and 9) is provided via an adhesive 35 on the back side of the back sheet 30 and in the vicinity of the region where the base absorbent body 10 exists on the front side and the holding portion 32. Yes. When the absorbent article 1 is used, the release sheet 34 is peeled off and the back sheet 30 is brought into contact with the inner side of the underwear, and the holding portion 32 is folded back to come into contact with the outer surface of the underwear, The absorbent article 1 is held on the underwear by the adhesive 35 interposed between the underwear and the underwear. In addition, since the release agent is applied to the release sheet 34, the release sheet 34 can be easily peeled from the back sheet 30 with the adhesive 35 left on the back sheet 30.

  In the present embodiment, the back sheet 30 as a sheet member is a thermoplastic and liquid-impermeable sheet such as polyethylene and polypropylene, but includes a thermoplastic and liquid-impermeable sheet, such as thin paper or nonwoven fabric. Laminated sheet-like members may be used.

  Like the base absorbent body 10, the top absorbent body 20 has an absorbent body material 12a as a liquid absorbent member made of pulverized pulp, a superabsorbent polymer, and a heat-fusible fiber. A liquid-permeable intermediate sheet 16 having a higher liquid holding power than the top sheet 14 is provided, and a top sheet 14 similar to the base absorbent body 10 is wrapped around the outer periphery thereof. The intermediate sheet 16 is a member having a density higher than that of the top sheet 14 and a high absorbability due to surface tension. By providing the intermediate sheet 16 inside the top sheet 14, the liquid that has permeated the top sheet 14 is allowed to flow from It is moved to the intermediate sheet 16 side where the liquid draw-in property is high.

  The top absorbent body 20 is formed to have a narrower width in the direction intersecting the longitudinal direction than the base absorbent body 10, and the top absorbent body 20 is disposed on the surface side of the base absorbent body 10 along the longitudinal direction. Then, only the top sheet 14 is folded on the front end 20a side and the rear end 20b side of the top absorbent body 20, and embossing is performed with an adhesive interposed between the folded top sheet 14. Reinforced portions 25 and 26 reinforced by the above are formed. In the reinforcing portions 25 and 26, the absorbent body material 12a and the intermediate sheet 16 do not exist.

  Further, the top absorbent body 20 is formed such that the reinforcing portion 26 on the front end 20 a side is finally joined to the front end side of the base absorbent body 10, and the rear end 20 b side is separable from the base absorbent body 10. Here, the main bonding is such that if the top absorbent body 20 and the base absorbent body 10 are intentionally separated, at least one of the top absorbent body 20 and the base absorbent body 10 is inevitably damaged. It shows a state in which it is firmly bonded to each other and cannot be peeled off. For example, as shown in FIG. 1, embossing is performed so that the deep groove embossing 19 is formed by thermocompression bonding. Here, the method of the main joining between the reinforcing portion 26 of the top absorbent body 20 and the front end side of the base absorbent body 10 is not necessarily limited to embossing. For example, the joining may be performed using only a hot melt adhesive. Good.

  The top absorbent body 20 is formed so that the absorbent body material 12 a protrudes outside the rear end edge of the base absorbent body 10 when the front end side is finally joined to the front end side of the base absorbent body 10. And in the site | part which the absorber raw material 12a of the top absorber 20 protrudes from the rear-end edge of the base absorber 10 at least, it is the same as that of the back sheet 30 mentioned above on the surface at the base absorber 10 side of the top absorber 20. A liquid impervious sheet 27 is provided. The liquid impervious sheet 27 is provided in order to prevent leakage of liquid from the back side of the top absorbent body 20 that is mounted separately from the base absorbent body 10, and is provided throughout the back side of the top absorbent body 20. It may be provided over the surface side so as to wrap the rear end side of the top absorbent body 20.

  Further, in the central portion of the top absorbent body 20 in the width direction, the amount of the absorbent body material 12a is set to other parts along the longitudinal direction in a substantially half region on the rear end side as shown in FIG. A thinner thin portion 12b is formed. By this thin portion 12b, the top absorbent body 20 is formed so as to be easily bent along the longitudinal direction so that the surface side becomes a mountain.

  Further, the hook material 22 for fixing the rear end 20b side of the top absorbent body 20 to the underwear during use on the surface of the base absorbent body 10 side of the portion 25b on the absorbent body material 12a side in the reinforcing portion 25 on the rear end 20b side. Is provided. This hook material 22 is a male material of a mechanical fastener, for example.

  Since the rear end 20b of the top absorbent body 20 protrudes from the outer peripheral edge of the base absorbent body 10, that is, the rear end edge, the absorbent article 1 has a long overall length as the absorbent article 1 and is portable. Since the rear end side is not joined, the position of the top absorbent body 20 is unstable at the time of manufacturing, for example. For this reason, when not in use, the rear end 20 b side of the top absorbent body 20 is folded, and the reinforcing portion 25 on the rear end 20 b side is temporarily joined to the rear end part of the base absorbent body 10. Here, the term “temporary bonding” refers to bonding to such an extent that the user can easily peel the top absorbent body 20 from the base absorbent body 10 without damaging the functions of the base absorbent body 10 and the top absorbent body 20. The peelable state is shown.

  As shown in FIG. 5, the top absorbent body 20 when not in use is folded at a length substantially coincident with the rear end edge of the base absorbent body 10 when stretched, and the folded portion is a folded position. It is folded back toward the front end side between the top absorbent body 20 and the base absorbent body 10 on the front end side. The folded portion of the top absorbent body 20 protrudes slightly rearward from the rear end edge of the rear end portion 20b of the top absorbent body 20 that is round-sealed at the rear end portion of the base absorbent body 10. The rear end 20 b is further folded back so as to face the back of the absorbent article 1.

  Further, when not used, the reinforcing portion 25 is temporarily joined to the rear end 20b side of the top absorbent body 20 at a portion that is round-sealed at the rear end portion of the base absorbent body 10. The portion where the base absorbent body 10 and the reinforcing portion 25 on the rear end 20b side of the top absorbent body 20 are overlapped is temporarily bonded by embossing, but the hook material 22 is also used when not used. It functions to temporarily bond the rear end 20b side and the top sheet 14 of the base absorbent body 10 together. Although the hook material 22 is used for temporary bonding here, the temporary bonding method may be only crimping by embossing, or may be bonded instead of the hook material 22, and is not limited thereto. Absent.

  Next, the packaged absorbent article 1 will be described. FIG. 9 is a diagram for explaining a state in which the absorbent article is packaged.

  In the packaged absorbent article 1, the holding portion 32 is bent to the front side, and the release sheet 34 that covers the adhesive 35 is provided on each of the holding portions 32 and the back side. The absorbent article 1 in a state where the release sheet 34 is provided is folded to the front surface side so as to be wound along the longitudinal direction together with the rectangular packaging sheet 36 disposed on the back surface side. At this time, the end on the rear end 10a side of the base absorbent body 10 in the packaging sheet 36 (hereinafter referred to as the rear end 36b of the packaging sheet 36) is extended longer than the absorbent article 1 and the adhesive is slightly applied. In addition, when the packaging sheet 36 is folded together with the absorbent article 1, it adheres to the side of the release sheet 34 provided on the holding part 32 folded on the surface side of the top absorbent body 20 on the non-peeled side with an extremely weak adhesive force. Is done. And the lead tape 38 provided in the front end 36a side in the packaging sheet 36 is affixed on the outer surface of the packaging sheet 36 by the side of the rear end 36b already bent with the absorbent article 1. FIG. The packaging sheet 36 folded together with the absorbent article 1 is used in a state in which the edge 36c along the longitudinal direction is adhered and sealed, and the absorbent article 1 is accommodated in the bag-shaped packaging sheet 36. Supplied to the person.

  When the packaged absorbent article 1 is peeled off by the user and the lead tape 38 is peeled off and the packaging sheet 36 is opened, the front end 1a is exposed. When the exposed front end 1a of the absorbent article 1 and the packaging sheet 36 with the lead tape 38 are peeled off, the absorbent article 1 can be easily taken out. The removed absorbent article 1 is placed at an appropriate position on the underwear with the release sheet 34 on the back side peeled off. And the peeling sheet 34 of the holding | maintenance part 32 is peeled off, it is return | folded to the underwear side, and it fixes to underwear by sticking with the adhesive agent 35 on the outer side of underwear. After the underwear to which the absorbent article 1 is fixed is pulled up to the body side, the user grips the portion on the rear end 20b side of the reinforcing portion 25 of the top absorbent body 20, that is, the grip portion 25a, so that the top absorbent body 20 is By pulling up, the temporary bonding between the base absorbent body 10 and the top absorbent body 20 is released, and the folded top absorbent body 20 is stretched. The stretched top absorbent body 20 is separated from the base absorbent body 10 while the portion where the absorbent body material 12 a is provided protrudes rearward from the outer peripheral edge (rear end 10 a) of the base absorbent body 10.

  Thereafter, the user moves the grip portion 25a in the longitudinal direction (substantially in the vertical direction), so that the top absorbent body 20 comes into close contact with the body excretion site and the body groove near the body excretion site. The position of is adjusted. With the top absorbent body 20 adjusted in position, the top absorbent body 20 is bent and fixed at the skin side surface of the back body of the underwear or the edge of the underwear. Thereby, the top absorbent body 20 is in a state in which the top absorbent body 20 is in close contact with the body by being disposed in close contact from the front side of the user's body to the rear side along the groove portion of the body. Is positioned, and the base absorbent body 10 is positioned substantially outside and below the body groove.

  According to the absorbent article of the first embodiment, since the absorbent body material 12a of the top absorbent body 20 projects in the longitudinal direction from the rear end 10a of the base absorbent body 10, the projected top absorbent body 20 causes the The liquid can be absorbed in a region wider than the base absorbent body 10 in the direction. At this time, since the base absorbent body 10 is shorter in the longitudinal direction than the top absorbent body 20, the size of the absorbent article 1 is made smaller than when the top absorbent body 20 and the base absorbent body 10 are formed to have the same length. It is possible. For this reason, it is possible to realize the absorbent article 1 capable of effectively absorbing the liquid while keeping the size small.

  Further, since the narrow top absorbent body 20 protrudes from the base absorbent body 10, the liquid flowing along the groove can be absorbed by placing the top absorbent body 20 along the body groove. Is possible. Further, since the base absorbent body 10 is overlapped with the top absorbent body 20, the liquid flowing straight downward can be effectively absorbed by the top absorbent body 20 and the base absorbent body.

  Furthermore, the absorbent article 1 of 1st Embodiment peels only the rear end 20b side of the top absorber 20 temporarily joined so that peeling is possible, and the top absorber 20 makes the base absorber 10 only the front end 20a side. It is possible to make it the state joined by. Then, the rear end 20 b side from which the top absorbent body 20 is peeled can be separated from the base absorbent body 10. For this reason, for example, it is possible to separate the top absorbent body 20 from the base absorbent body 10 and reliably and easily enter the body groove to absorb the liquid.

  Further, a back sheet 30 is provided on the surface of the base absorbent body 10 where the top absorbent body 20 is not joined, that is, the back face, and a liquid impervious sheet 27 is provided on at least a projecting portion of the top absorbent body 20. Therefore, the part where the top absorbent body 20 and the base absorbent body 10 are overlapped by the back sheet 30 provided on the base absorbent body 10, and the projecting part of the top absorbent body 20 is the projecting part. The liquid impervious sheet 27 provided can prevent liquid leakage from the top absorbent body 20 and the base absorbent body 10.

  In the present embodiment, the example in which the rear end 20b side of the top absorbent body 20 can be separated from the base absorbent body 10 has been described. However, the present invention is not limited to this. For example, the top absorbent body 20 overlaps the base absorbent body 10. The entire region may be bonded so as not to be peeled off. In this case, at the portion where the top absorbent body 20 and the base absorbent body 10 overlap each other, the top absorbent body 20 and the base absorbent body 10 both absorb the liquid and cannot be absorbed by the top absorbent body 20. The portion protruding from the base absorbent body 10 is arranged along the groove of the body while realizing a structure that reliably absorbs the liquid by the base absorbent body 10, and the liquid that leaks along the groove is disposed on the top absorbent body. 20 can be absorbed.

<Second Embodiment>
FIG. 10 is a plan view showing the surface side of the absorbent article according to the second embodiment.

Further, the body contact surface side of the top absorbent body 20, that is, the side on which the intermediate sheet 16 is provided is disposed so as to face the surface of the base absorbent body 10. A liquid impervious sheet 27 is provided over the entire area. And the reinforcement part 26 on the opposite side to the holding part 25a of the top absorbent body 20 is finally joined on the rear end side of the base absorbent body 10, and the reinforcing part 25 on the holding part 25a side can be separated from the base absorbent body 10. Is formed. Further, when not in use, the reinforcing portion 25 on the gripping portion 25 a side of the top absorbent body 20 is temporarily joined to the front end portion of the base absorbent body 10.

  When the absorbent article 2 of the present embodiment is used, the release sheet 34 on the back side is peeled off and placed at an appropriate position on the underwear. And the peeling sheet 34 of the holding | maintenance part 32 is peeled off, it is folded by the underwear side, and the absorbent article 2 is fixed to underwear by sticking on the outer side of the underwear with the adhesive agent 35. FIG.

 Thereafter, the user holds the grip portion 25a of the top absorbent body 20 and pulls up the top absorbent body 20, whereby the temporary joining between the base absorbent body 10 and the top absorbent body 20 is released. Further, the user separates the top absorbent body 20 from the base absorbent body 10, and sets the end on the gripping part 25 a side as the other end of the top absorbent body 20 in the longitudinal direction to the end on the main joined side. In FIG. 5, the base is moved to the rear side beyond the rear end 10a of the base absorbent body 10. At this time, the body contact surface facing the surface of the base absorbent body 10 is directed to the body side. And the underwear to which the absorbent article 2 was fixed is pulled up to the body side.

  When the user moves the grip portion 25a upward, the position of the top absorbent body 20 is adjusted so that the top absorbent body 20 is in close contact with the groove of the body. With the top absorbent body 20 adjusted in position, the top absorbent body 20 is bent and fixed at the skin side surface of the back body of the underwear or the edge of the underwear. Thereby, the top absorbent body 20 can prevent the liquid flowing along the groove portion of the body from leaking to the rear of the base absorbent body 10.

  According to the absorbent article 2 of the second embodiment, the top absorbent body 20 does not protrude from the base absorbent body 10 before the top absorbent body 20 is peeled from the base absorbent body 10. Moreover, the top absorbent body 20 is moved from the rear end 10a of the base absorbent body 10 by moving the base absorbent body 10 peeled from the top absorbent body 20 from the end 20a portion where the top absorbent body 20 is permanently joined. Protruding. For this reason, before the top absorbent body 20 is peeled off, the absorbent article that allows the top absorbent body 20 to protrude from the base absorbent body 10 and effectively absorb the liquid after peeling while keeping the size small. 2 can be realized.
